研究Salen-卟啉配合物催化氧化二苯醚、二苯乙烷、二苯甲烷木素模型物的降解产物.利用红外光谱和气相色谱-质谱(GC-MS)分析二苯型木素模型物在Salen-卟啉配合物催化氧化下的降解产物.通过对比转化数(TON)与转化率(TOF),发现催化剂的存在使反应底物发生转化;Zn PSC6的催化能力强于Co(salen)的催化能力.依据催化氧化后的二苯型木素模型物降解产物,发现Salen-卟啉配合物的催化氧化能使二苯型木素模型物中醚键、Cβ-Cγ、Cα-Cβ联接断裂,并且使苯基减少,产生了苯酚、苯甲酸等降解产物.
The degradation products of diphenylether, diphenylethane and diphenylmethane lignin catalyzed oxidation of Salen-porphyrin complexes were studied by using infrared spectroscopy and gas chromatography-mass spectrometry (GC-MS) The catalytic degradation of Salen-porphyrin complex was studied by comparing the conversion number (TON) with the conversion rate (TOF). The catalytic conversion of Zn PSC6 was found to be stronger than that of Co (salen) Catalytic oxidation based on the degradation products of dibenzene-type lignin model and found that the catalytic oxidation of Salen-porphyrin complexes can make ether bond, Cβ-Cγ, Cα-Cβ linkages Break, and reduce the phenyl group, resulting in phenol, benzoic acid and other degradation products.
